Abstract
To assess adverse effects that might be caused by an event resulting in high levels of barium in drinking water, rats were gavaged with barium chloride (BaCl2 at dosage levels of 30, 100, and 300 mg/kg in a 1-day study and at 100, 145, 209, and 300 mg/kg for 10 days) and the effects were determined. LD50 values for male and female rates were found to be 419 (352-499) and 408 (342-487) mg/kg BaCl2, respectively. In the 1-day exposure study, decreases in body weight and liver/brain weight ratios and increase in kidney weight as a percentage of body weight appeared to be related to barium ingestion at 300 mg/kg. After 10 days of exposure to barium, survival of females was substantially lower at 300 mg/kg. A reduction in ovaries/brain ratio at 300 mg/kg appeared to be barium-induced. There was a decrease in BUN at 300 mg/kg in males and at all dose levels in females. No other effects were attributed to barium. Histopathological findings were negative in both the 1- and 10-day studies. It is concluded the short-term oral exposure to BaCl2 at doses up to 209 mg/kg produces no significant adverse health effects.
